Detailed explanation-1: -The ancient Greek astronomical calculating machine, known as the Antikythera Mechanism, predicted eclipses, based on the 223-lunar month Saros cycle.
Detailed explanation-2: -One of the clearest patterns for predicting solar eclipses is the Saros cycle, first observed by the ancient Mesopotamians. Within a Saros series, solar eclipses occur at intervals of 223 lunar months. These cycles each last around 1, 000 years-eclipse after eclipse after eclipse.
Detailed explanation-3: -The eclipse prediction scheme is implemented through descriptive glyphs, inscribed round a 223-month Saros Dial at the rear of the Mechanism: a glyph in a particular month indicates a predicted eclipse.
Detailed explanation-4: -First discovered by divers in a Roman-era shipwreck in 1901, researchers have puzzled over the extraordinary Antikythera mechanism for decades. The hand-held device dates back 2, 000 years and predicted astronomical events, such as the movement of the planets and lunar and solar eclipses, for its ancient Greek users.
